To all whom it may concern:

Be it known that I, EARL T. BENNINGTON, a citizen of the United States, residing at Colonial Heights, in the county of Guyahoga and State of Ohio, have invented a certain new and useful Improvement in Carriers for Overhead Carrier. Systems, of which the following is a full, clear, and exact description.

This invention relates to carriers for overhead carrier systems and particularly monorail systems, and has for its object to provide for the rapid assembling or disassembling of carriers, and for the construction of a wide variety of types and sizes of carriers from a relatively few standard parts or units so as to eliminate entirely, or reduce to a minimum special engineering work' and with depending portions adapted to be connected by load bars which can be connected Without the necessity for permanent fastening to pairs of heads of any of the standard designs.

The invention may be further briefly summarized as consisting in certain novel details of construction and combinations and arrangements of parts which Will be described in the specification and po1nted out in the appended claims.

In the accompanying sheets of drawings wherein I have shown three different forms of carriers among a number which can be produced in carrying out" the multiple unit idea, Fig. 1 is a side view of a carrier composed of what may be termed a trolley head, a motor head and a load bar; F1g. 2 is an end view of the samelooking toward the left of Fig. 1; Fig. 3 is a sectional view along the line 3-3 of Fig. 1 looking downwardly; Fig. 4. is a sectional view 'substant1ally along the line H of Fig. 3; Fig. 5 shows a double carrier composed of a carrier such as shown in Fig. 1 and a trailer connected together by a load bar; and Fig. 6 is a view of a double carrier such as illustrated in Fig. 5 and composed simply of two similarly connected trailers.

Referring now to Fig. 1, the carrier here shown is composed of three units including what may be termed a trolley head 10, a motor head 11 and a'load bar 12, both the trolley head and motor head having at their upper ends track wheels 13 adapted to engage, in this instance, a monorail 14. The

motor head carries an electric motor 15 geared to the corresponding track wheels 13,

the gearing being indicated in Fig. 1 and being shown in part in Fig. 2.

Before taking up the details of any of these parts reference will be had to Figs. 5 and 6, and first to Fig. 5 which shows a double carrier adapted to convey twice the load of the carrier of Fig. 1, this carrier including a carrier similar to that shown in Fig. 1 and composed of a trolley head 10, a motor head 11 connected by the load bar 12, and in addition it includes a'trailer composed of a pair of trailer heads 16 connected by a load bar 17 and the two load bars 12 and 17 are connected together by a load bar 18.

The carrier shown in Fig. 6 is composed of two carriers such as shown in Fig. 5, connected by a load bar, and therefore comprises in effect two trailers each having trailer heads 16-16 connected by a load bar 17 with the two load bars 17 connected by an auxiliary load bar 18 similar to that illustrated in Fig. 5.

The above described carriers of Figs. 1, 5 and 6 illustrate simply three of a vast number of carriers which can be formed from the three heads or head units 10, 11 and 16, and load bars, and I wish it clearly understood at this point that while I have illustrated simply three carriers, a great variety of other carriers modified in one way or another can be formed without any alterations in the standard trolley, motor and trailer heads, and require only slight modifications in the load bars.

Before describing certain details which are applicable to all the three types of heads here illustrated, it might be mentioned that the trolley heads of Figs. 1 and 5 are similar in construction to the trailerv heads of Figs.

Each trolley head 10, motor head 11 and.

trailer head 16 is composed of two side plates 10211 or 16'" as the case may be, which plates are suitably spaced apart at the top to accommodate the upper track rails. Both plates of the trolley and trailer heads are exactly the same, andtherefore the illustrations in Figs. 1, 5 and 6 for these heads will be sufficient, but in the case of the motor head illustrated in Fig. 2, as well as in Figs. 1 and 5, one of the side plates is offset to accommodate the motor and some of the other parts. p

The side plates of all three types of plates are at their lower ends spaced apart and secured by bolts 20 to a spacing member preferably in the form of a ribbed casting 21 having 'at its four corners on each side, ears through which the bolts 20 pass. Each of these spacers or spacing castings 21 is provided with a vertical socket; 22 which receives a downwardly extending stud or swivel bearing member 23 of a member 24 secured to the load bar. This constitutes the sole fastening means between the two heads and the associated load bar, for with this construction the two heads and load bar are securely fastened together, and, in such sential, I prefer to extend a bolt 25 through the plates of each trolley and trailer head to prevent the corresponding end of the load bar lifting out of the socket.

Thus the heads of each carrier, whether of the single type, such as illustrated in Fig. 1, or of the double type, such as illustrated in Figs. 5 and 6,. can be readily assembled or taken apart since the heads are fastened together simply by the insertion of the bar members in the sockets of the spacers, and no permanent fastening by rivets or bolts is necessary.

In the double carriers the load bars 12 and 17 of Fig. 5,.o-r the load bars 1.717 of Fig. 6 are-connectedto the connecting load bar 18 by brackets 26' secured to and depending from the load bars 12 and 17 and provided with cylindrical lower portions on which the end members 27 secured to each load bar 1-8'are fitted and have a swivel action, and the load bar is held in'pl'ace in each instance by nuts 28 screwedflonto the threaded lower ends t the memb rs-=26..

Thus it will be seen-that little if any engineering or desigmng is required to be done to makeup a carr er to suit any particular load conditions for the heads can be madeup in lots and the construction of a carrier requires simply the selection of the desired heads and of the desired load bars which may or may not be'of standard form.

It was heretofore stated thata great variety of carriers could be formed or constructed utilizing any of the three standard heads and suitable load bars, and while it is not feasible to describe all the carriers that could be thus made, I might mention that a double carrier suchas shown in Fig. 5 could be readily modified by the substitution of a motor head for one of the trailer heads 16, or one of the trailer heads 16 of Fig. 6 could be replaced with a trolley head as when the carrier is to be equipped with an electric hoist. Other changes of like nature could be made to vary the precise form and even carrying capacity of the carrier.

Having described my invention, I claim:

1. A carrier for overhead carrier systems composed of two heads having trackwheels at their upper ends and a load bar extending between and having a swivel connection with the lower portions of both heads, said load bar having downwardly extending swivel bearing members fitted intosockets of the heads, said sockets being between a pair of depending portions ofthe head.

2. A carrier for overhead carrier systems comprising a pair of heads with track wheels at their upper ends and having a pair of laterally spaced members provided at their lower ends with socketed spacer members, and a load bar connecting said heads and provided with swivel bearing studs extending into the sockets.

3. A carrier for overhead carrier systems comprising a pair of heads each comprising a pair of plates spaced apart at the top to accommodate track wheels and at the'bottomhaving socketed spacing members, and a load bar extending between said heads and having a swivel connection with each, the connection being formed by a bearing stud on the load bar extending intoqthe socket of the corresponding spacing member ofthe head.

' 4-. A multiple unit carrier for overhead "carrier systems composed of twoheads with a pair of laterally spaced members with socketed members at their lower parts, and a load bar having at its ends downwardly extending swivel bearing studs which are inserted in said sockets to form the connecting means between each head and the load eachlset of: heads having a pair of laterally 1:30 i
